Brief Summary:
The purpose of this study is to provide sildenafil therapy to eligible adult patients with pulmonary arterial hypertension (PAH) and to the patients who completed the A1481142 study for the treatment of PAH in Poland. Only safety and tolerability data will be collected in these patients.

Condition or disease Intervention/treatment
Pulmonary Hypertension Drug: sildenafil

Study Type : Observational
Actual Enrollment : 32 participants
Time Perspective: Prospective
Official Title: A Local, Multi-Centre, Open Label Access Study, To Provide Sildenafil Therapy To Eligible Adult Patients With Pulmonary Arterial Hypertension For One Hundred Twelve Weeks / Prior To Reimbursement And Availability For Patients In Poland.
Study Start Date : June 2006
Actual Primary Completion Date : March 2009
Actual Study Completion Date : March 2009

Intervention Details:
  • Drug: sildenafil
    tablets, 20mg, TID, 112 weeks at the maximum
  • Drug: sildenafil
    tablets, 20mg x 4 (80mg), TID, approximately 70 weeks

Primary Outcome Measures :
  1. Number of Subjects With Adverse Events (AEs) and Serious Adverse Events (SAEs) [ Time Frame: Baseline up to 116 Weeks ]
    Adverse event = any untoward medical occurrence in a subject administered study medication regardless of causality including abnormal test findings, clinically significant signs/symptoms, changes in physical examination findings, hypersensitivity, progression/worsening of underlying disease, and exposure in utero. Serious adverse event = any untoward medical occurrence at any dose that resulted in death, was life-threatening, required inpatient hospitalization or prolongation of hospitalization, or resulted in persistent or significant disability/incapacity or congenital anomaly/birth defect.
